Brief Summary:
PIONEER-II RCT trial is a prospective, multicenter, randomized, non-inferiority registry trial. 539 subjects from about 40 interventional cardiology centers in China will be enrolled to evaluate In-stent late lumen loss(LLL) as the primary endpoint at 9 months. And all the subjects will be followed up to 5 years to attain the data of the secondary endpoints.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Device: BuMA Supreme Device: BuMA™ Not Applicable

Detailed Description:
Realizing even more uniform and complete endothelial coverage, BuMA Supreme™ biodegradable drug coating coronary stent system comprises a new generation of biodegradable drug eluting stent under development by SINOMED. BuMA Supreme™ reconfigures BuMA™ DES utilizing a high caliber cobalt chromium platform coated with rapidly degrading PLGA scaffold.

Arm Intervention/treatment
Experimental: BuMA Supreme group
This group contains 319 subjects. Among them, 220 subjects will be implanted with regular specifications and 99 subjects with narrower, wider or longer ones.
Device: BuMA Supreme
Stent platform: cobalt-chromium alloy

Active Comparator: BuMA™ group

Device: BuMA™
Stent platform: stainless steel

Primary Outcome Measures :
  1. in-stent Late Lumen Loss, 9M [ Time Frame: QCA at 9-month follow-up window ]
    The primary endpoint is in-stent Late Lumen Loss (LLL) at 9-month after stent implantation as assessed by off-line quantitative coronary angiography (QCA).

Secondary Outcome Measures :
  1. Stent implantation success rate [ Time Frame: 5 years after PCI ]
    The stent implantation success rate includes device success, lesion success and clinical success.

  2. Binary restenosis rate [ Time Frame: 9 months ]
    Binary restenosis was defined in every segment (proximal, distal, and stent) as a >50% diameter.

  3. in-segment LLL [ Time Frame: 9 months ]
    to evaluate the in-sigment Late Lumen Loss (LLL) at 9-month after stent implantation as assessed by off-line quantitative coronary angiography (QCA).

  4. diameter stenosis degree [ Time Frame: 9 months ]
    to compare the lumen diameter at 9-month after stent implantation with the baseline diameter as assessed by off-line quantitative coronary angiography (QCA).

  5. Device-oriented Composite Endpoint (DoCE) [ Time Frame: 1, 6, 12 month, and annually up to 5 years post procedure ]
    Device-oriented Composite Endpoint is defined as cardiac death, target vessel MI, or clinically-driven target lesion revascularization (TLR).

  6. Patient-oriented Composite Endpoint (PoCE) [ Time Frame: 1, 6, 12 month, and annually up to 5 years post procedure ]
    Patient-oriented Composite Endpoint is defined as all cause death, all myocardial ischemia (MI), or any revascularization.

  7. Academic Research Consortium(ARC) defined stent thrombosis [ Time Frame: 5 years after PCI ]
    Definite and probable stent thrombosis during acute, subacute, later and very late phase.
